To all whom it concern:

I Be it known, that I, Join-mums STUMPF,

a subject of the German Emperor, and resident of Balz, near Vietz, near Landsberg-onthe-Wa'rthe,'. Germany, have invented new and useful Improvements with regard to 'Slid-ing Windowsfof which the following is a specification. 7

My invention relates to sliding windows, which are guided by pins inv grooves in the window frame, and are raised bycounter weights. These windows can also be :ti-lted into the room and are prevented from being .raised by the counter poi'scs, when tilted by pins fixed to the window frame under which a plate fixed to which slide in a circular groove'in a plate fixedto the sash.

. Figure 1 1s a part sectiofial view of the right-handframe Z withtheJguide grooves bars3 and 7. 'Fig. 2 is a horizontal .section throughthe tight double window frame. Fig. 3 is' a side view Ma wood. Fig. 7 is and securing keyr Fig. 11 is a'top view oftop and bottom pair of double-sashes in locked position. :Fig. 4 shows a part sectional, vertical front view .of the'right hand frame with the .top sashes in the lower posi-' 'tion. Fig. 5 is a top viewof =thelocki ngv arrangement of each pair of sashes. Fig. 6 is a vertical; section through. the bolt in: the

is a bolt 9 with partly. cut up frame work the bolt sleeve 9 with spring 9 beneath.

The double sash consists of the upper pair of sashes O, O and the lower pair ofsashes U, U. i Each pair is connectedby two hinges 17, which are screwed on 'tothe lower ends of the sash frames, as well as bytwolocking in pieces, both of which consists of sleeves- 2O and,20-, the first sleevebeing inserted into the surface of the top' frame of the sashes O, U respectively,

respectively in such a manner, that a" squarely "bent bolt 21 *can be "-pushed in, and which in consequence of the recess 22 can also be drawn'back again. v When pushed in',-the respective pairs of sashesf'are kept against one another. v

the sash passes, or by pins .in the groove 6.

whilegthe second sleeve. isinserted'in the' face of the frame Of II In the locked position both pairs of sashes are in the position as illustrated in Fig. 3, namely, vertically placed to each other against the weather frame \V, Figs. 1 and 2,

and are closed in such a way-that a turning bolt 8,. which is secured to both vertical frames of-the' sash U, catches into a plate 8? having a slot therein, whereby not only the lower but alsothe upper pair of sashes which are pressed against the top cross head of the window frame by means of the cross .bead 1, while the rail: ofthe lower sash U presses the bottom of the two said sashes O, U against W.

Into the surface of the right and left hand frame work Z, are cut vertical grooves 5, 6, the latter. below running at a slanting line into 5.

The groove 5 serves as a guide'to the hori- 'zontally projecting cylindrical guide pins 2 in the lower corners of 0, while the horizontally projecting round pins -t,'situatedin. the lower corners of the sash U, are guided balanced by means of wire ropes 11 fastened on pins 2, are conveyed over small pulleys 10*" to the counterpoises C, similar, counter poises C" in the same manner balancing the windows ropes ll, which are fastened on pins 4 and conveyed over pulleys 10.

.The windows 0, O are which U, U by means of wire A vertical bead 7 is screwed to the center of the window frame Z, the said bead having an inclined bottom and reaching about half waydown' the window frame, andto the window frame is also attached a bead 3 with a rail 3 On elevating the pail-U, U, which has been previously tilted somewhat, the same fits with its top end between the strips" 1 7 and 3 on account of the latter having slanting bottom ends, and slides up in said strips,

pins .4; in the grooves 6. I

When pulling down the upper pair of sashes, they next slide between thestrip 7 and the projecting weather frame N, Fig. 2, while below the pair 0, O is guided by the pins 2 in the grooves 5.

On the frame Z or on while below the sash pair, is guided by the sition by means of a coil spring 9 and guided the strip 3 is arranged a box like portion 9 with a horizontally protruding round bolt 9, possessing-a slot; said bolt 9 .is' kept inits supporting po by a rivet 9 in the slot in the bolt, while a J sliding piece 9, which can be put through a slot 9 in the box 9, and screwed into 9 forms an operating knob.

The pushing backwards (6f the lock bolt 9 can be prevented by means of a tightly screwed plate spring 9*, arranged in the frame work so that'the flange 9 formed by bending the end of spring 9* at a right angle, will project behindthe rear end. of bolt 9 when the lock bolt is drawn forward. To be able to push 9 backwards, a securing key 9 Fig. 10, provided with a'cross pin 9 is inserted into the suitably shaped hole 9 of the plate 9, Fig. 11, pressing back the spring I a horizontal position into the room.

which is after which the window U,

- To make the cleaning of the sash surfaces possible, which are defining the inner air space of each sash pair, the bolts 21 of every window pair are drawn out of the sleeves 20, O is lifted up on the hinges l7.

In the case of'tilting back, the edge of the respective pair of sashes pushes back the lock bolt 9 in consequence of the'slanting portion 9, after which 9 jumps forward again and prevents unintentional tilting over of the sashes towards the room.

In order to prevent the tilting pair of sashes during their swinging, from being drawn upby the counterpoises the guide pin 2 as well as 4 possesses cross pins 4 Figs. 3, 4i and 9, which on the oscillation of the window fix. themselves in the above described open sector ofa plate 12, which is screwed into both frames Z. In consequence however of the navoidable gradal wearing elf of the metal pieces 2, 1, and the plate sector,

the said fastening device might get defective in the bearings, so that I arranged for a special securing device. The corner plates 14 with guide pins2, 4, possess circularly shaped projecting corners 14, which at the instant, when the toppart of each pair of sashes passes the bolt 9, slide under the round pin 13, projecting from under the plates 12, and prevent thereby the drawing up of the sash.

This necessary securing device, can besides be arranged in such a way that the corner plates 23 are made with hooks 23, which on turning the sash, reach under a round pin 16" arranged on the plates 16, while on swinging the-pair of sashes further, the cor-v ner plates 23" reach under a round pin 16 projecting from 16. While each bottom sash U is as much as the width of the strip piece 25 longer than the top sash O, the tops of 0 have pins 19 fixed to them, which on O, O standing becomes low, lean gently against the strips 7 and prevent by tiis means the pair of sashes from tilting towards the bolt 9. For 19, there are recesses 19 provided in the head strip 26. By this it appears that this double sash only requires the handles in order to open and clean it like an ordinary sash, and it makes nevertheless theinner as well as the outer sash .air tight on all sides.

IVhen using single sash, the outer sashes U andO and the locking pieces 20, 2 and 21, as also the hinges 17 are simply omitted, while everything else remains the same.

Having fully described my invention, what I claim and desire to secure by Letters latent is o 1. The combination with a sash frame provided with grooves 5 and (5, converging into one near their lower ends, upper and lower sashes, weights for balancing the sashes, studs located only near the lower ends ol each sash, said studs operating in the grooves, beads against which the outer sides of the two sashes abut when in closed position, beads parallel with the upper portions of grooves 5 and 6, and terminating above the lower sash to form guides for said lower sash when raised from normal position, a movable device below the guiding beads and adjacent the upper end of the lower sash for directing the lower sash when tilted in the guides, said device when withdrawn permitting of either the upper or lower sash being turned horizontally on the studs in the sash frame, and means for preventing the weights raising the sashes when their upper ends are tilted past the movable device.

2. In combination, a window frame, inwardly extending beads on the outside of the frame, inwardly extending beads on the illside of the frame, said latter beads extending downwardly to a point substantially above the upper rail of the lower sash, beads on the upper portions of the frame intermediate the outer and inner beads to provide sash guides, the sides of the frame in the guides having grooves 5 and G, grooves (3 communicating near the bottom with grooves 5, the beads on the inside of the frame and the intermediate beads being parallel with the upper portions of the grooves!) and 6, upper and lower sashes, weights for balancing the sashes, the upper sash adapted to fit in the guides adjacent the outside beads and the intermediate beads when in closed position, studs near the lower ends of the sashes and operating in the grooves 5 and (i, the studs and the guides serving to direct the sashes in the proper path of movement, an extension on the lower sash for holding the upper sash against the outside bead, a locking device for holding the lower sash in closed position, a sliding bolt located below the inside and intermediate beads to guide the upper end of the lower sash when tilted in when raised in grooves 6, the inner beads' the guides formed between the intermediate beads and the inside beads to direct the studs on'saicl sash in grooves 6, when raising it, said bolt when withdrawn also permitting of horizontal turning of either sash in the frame, and means preventing the weights raising either sash when'its upper end' is tilted past the withdrawn bolt.

3. The combination with a sash frame provided with grooves 5 and 6, converging into one near their lower ends, an upper sash,

a lower sash, weightsto balance the sashes, studs near the lower ends of the upper and lower sashes adapted to slide in said grooves, outer and intermediate beads on the frame above the lower sash for forming a guide for the upper sash, said latter beads being parallel with the upper portions of the grooves 5 'and 6, the; intermediate beads terminating above the upper end of the lower sash, inner beads forming with the intermediate'beads guides for the lower sash extending from, the'top of the frame to a point above the upper end of the lower sash,

a sliding'bolt to direct the lower sash when tiltedin the latter guides, said-bolt being 10- gated so that when withdrawn the lower sash may be'turnedoutwardly on its studs, and

means for preventing the weights raising the past balancing the sashes, means for locking said two members together, studs located near the ends of the upper and lower sashes which fit in the grooves, a guide parallel with the grooves 6 above the normal position of the,

lower sash and in which said sash is adapted to slide, a bolt in alinement with the guides V to directthe lower sash thereto when it is tilted, said bolt when withdrawn permitting of the'sashes being turned horizontally in the frame, and means for preventing the weightsraising the sashes when their-upper ends are tilted past the withdrawn bolt.
